PIPE-HOLDER.

SPECIFICATION forming part of Letters Patent No. 552,951, dated January 14, 1896.

. Serial No. 545,549K (No model.)

To all wil/0m, t may concern.-

Be it known that we, JOHN A. BowER and GEORGE M. BOWER, citizens of the United States, residing at Buffalo, in the county of Erie and State of New York, have invented a new and useful Improvement in Pipe-Holders, of which the following is a speciiication.

This invention relates to a holder designed more especially for the use of plumbers for holding a pipe in position in making a wipejoint or for any other purpose.

Our invention has for its object to produce a convenient holding device of this character which can be quickly clamped to a pipe and which can be readily adjusted to the position of the pipe.

In the accompanying drawings, Figure l is a side elevation of our improved holder, showing the clamp adjusted to receive a horizontal pipe. Fig. 2 is a similar view showing the clamp adjusted to a vertical pipe. Fig. 3 is a sectional elevation of the holder as shown in Fig. l. Fig. et is a top plan View of the same. Fig. 5 is a similar view showing the main adjusting-sleeve and the socket carried by the same in horizontal section. Fig. 6 is an enlarged section al elevation of the base of the standard.

Like letters of reference refer to like parts in the several figures.

A represents a pst or standard carrying the parts of the holder and designed to be temporarily secured to the iioor, a wall or other support. The standard is provided at its lower end with a base plate or iiange a and an attaching-screw a. This screw is preferably made removable, as shown in Fig. 6 of the drawings,so that it may be readily renewed when worn out or broken. The base-plate is for this purpose formed with a central opening a2, in which the head of the screw, which is preferably an ordinary wood-screw, is seated, and the screw is held in place by the lower end of the standard which is screwed into an,

internally and externally screw threaded bushing d3, which is in turn screwed into an internally-threaded socket a4 formed in the upper side ot' the base-plate a. Upon unscrewing the standard from this bushing the attachingscrew can be removed and Vreplaced by a new one.

B is a sleeve or collar made vertically adjustable on the standard A and carrying the clamping device which grasps the pipe. This sleeve is provided with a set-screw Z1, whereby it is secured in place after adjusting it to the desired elevation.

The pipe-clamp consists of an inner jaw C and an outer jaw D, which is movable toward and from the inner jaw. The inner jaw is provided with a horizontal stern or shank c, which is adjustably secured in a socket e arranged on the vertically-adjustable sleeve B, the stern being adjustably held in position by a set-screw e arranged in a screw-threaded opening formed in the socket c and bearing against the stem. The outer jaw D is supported by a shifting rod F, which is lon gitudinally movable in a socket g arranged on one side of the relatively-liked inner jaw C, and which is secured in said socket by a setserew g'. The outer jaw has an arm or shank CZ provided at its inner or lower end with a hub or collar d', which is capable of sliding upon the shifting rod F toward and from the socket g.

h is a clamping or thumb nut applied to the externally screw-threaded outer portion of the shifting rod F and adapted to bear against the sliding hub of the outer jaw, so as to clamp the latter against the pipe placed between the two jaws.

In using our improved holder, after securing the post or standard adjacent to the pipe to be held, the jaws are placed at the desired elevation by properly adjusting the sleeve B on the standard and they are adjusted to the angle or position of the pipe by loosening the set-screw e. of the stem of the inner jaw,which permits the jaws to be turned to a vertical, horizontal or any intermediate position, said set-screw being again tightened after adjust ing the jaws. The outer jaw is next separated from the inner jaw to receive the pipe, by loosening the set-screw g' of the shifting rod F and the outer jaw is then slid against the' pipe and the set-screw tightened, after which the pipe is firmly clamped by tightening the thumb-nut h, which forces the outer jaw toward the inner jaw. The greater part of the movement of the outer jaw is thus effected by sliding the shifting rod in its socket, which can be quickly done, and the pipe is then tightly clamped by a comparatively few turns of the thumb-nut h. The holder is as slide on said supporting rod toward and fromk readily released by loosening this thunrbfnut and the set-serewg and Sliding the outer `j aw away from the inner jaw.

Our improved holder is a very Convenient accessory, as it holds the pipe reliablyin place and gives the plumber the `free Yuse of both hands.

le elaiin as ourinvention- 1. krlhe eeinbination with a post or standard and an inner jaw connected tl'ierewith, of a supporting rod arranged to slide lengthwise on the inner jaw, an outer jaw arranged to the inner jaw, and a Clamping or adjusting device whereby the outer jaw is moved on said red toward the inner jaw7 substantially as set forth.

2. The combination with a post or Standard, of a Sleeve made verticallyadjustable on said post and having a socket provided with a set screw, an inner jaw having a shank adjustably arranged in said`soeket,- a supporting rod arranged te slide lengthwise on said inner jaw, an outerk jaw arranged to slide on said supporting rod, and a clamping or adjusting nut,`whereby the enter jaus moved toward the inner jaw, Substantially as ser forth.

. a. The Combination with a post or standard and an inner jaw arranged thereon, and hav f ingia socket, of a shifting rod secured in said socket, an outer jaw arranged to slide on said shifting rod,` and a clamping nut applied tok Said Shifting rod for moving the outer jaw on the saine, substantially as set forth.

The eombi n ation with a poster standard an inner jaw niadie vertically adj ustable thereon and provided kwith a .socket having a ser Screw, .fr-'shifting rod Secured ink said socket. an outer j aw having a hub Larranged to` slid e on said shifting rod,anda th unil) nut applied to said rod and bearing against the outer side YOt' said hub, substantially as Set Jforth.
